A barrier to the isoreticular expansion of flexible metal-organic frameworks is their complex breathing behavior, which can lead to pore closure upon solvent exchange and removal. Here we show that chemical cross-linking stabilizes the open form of a flexible aluminum framework with large 17 Å pores.
